Antares with Polarie, 60Da and 50mm lens

[IanP]

This image is the product of 2h (2x60x1min @ ISO2500) of exposure captured in two sessions using POLARIE.
Here in Perth the geographic and magnetic south differ only by approximately 1deg, so setting up the POLARIE is a piece of cake: a little bit more than 30deg (31.5) as the angle of elevation and almost in line south with a compass.
Processed in PixInsight with MBias and MDark applied.

Always a beautiful perspective. The Antares Rho complex is something of a jewel studded pendant, strung on long threads of dust. Very nice.

That really is a good image Ian!

Nice and sharp, subtle colour.

Cheers,

Justin.

Nice image Ian - it's becoming one of my favorite subjects too.
Was that taken in Perth? Or did you get out a bit?
Cheers,
Andrew.

Great looking photo Ian.

One of the most beautiful parts of the sky and you have photographed it perfectly..what a great composition!

The Canon 60Da, at 2500 ISO, has captured amazing colour and details.

A beautiful capture Ian

Thanks David, Ross and Carlos ..

I’m still experimenting with higher ISOs but it looks like, in my case, it works just fine.

Missed that one. Superb field.

[Elio]

Nice image, I love widest field

At 50mm no need a great precision, here you can find mine version, using a poor eq3 with sideral rate, subs are about 300s

Thanks Marc and Elio.

The framing in your version is almost the same as in mine, just the colour balances are touch different, but that is always a matter of personal preferences.

hi ian..... love the pic firstly!
what lens did you use and aperture? on Antares you can see the
blades(?) of the iris, is that right and is that what it is?
I have a 60da and a Samyang 35mm plus a good LP filter and don't seem to be able to extract much exposure before the sensor becomes polluted
I am in mount hawthorn so our skies are really the same
did you use an LP filter too?

Hi Pat,
From Churchlands, I never take shots in CBD direction è eastlish. Most of my shots have been taken right up, looking slightly south-west.
In this instance I used 50mm, F1.4, slowed to 5.6.
This particular lens produces that “nice” shape of brighter stars with blades.
I have Astronomik CLS clip filter but I don’t use it.
In my opinion, and some users don’t share it, these filters irreversibly spoil the colour balance and also remove “something” from the data.
